So now that I’ve said that out loud, I’ve gone back and taken a thousand points from log and plotted them in excel.

Looks a *lot* more like sawtooth than noise. Hmm. I might have to reconsider.

I am not confident that I could tell the difference between noise in the phase detection system and PPS jitter variations that small. If the PA6H receiver gave sawtooth corrections, I’d be able to do better.
